I'm not sure why Ooma has not made any mention of this anywhere but as of January 1, 2026, Nomorobo is not supported on landlines and VOIP services.

Call blocking preferences still has an option for how to treat "suspected spammers powered by Nomorobo". So, this option is worthless now.

In addition, Ooma has also changed the levels of call blocking and the options in the call blocking preferences, but their documentation still shows the original slider and options.
